Carpal tunnel syndrome: report of 430 operations.

Analyzed are data on 430 operations in 326 patients for median nerve compression at the wrist. Follow-up data from a patient self-evaluation questionnaire were available for 71% of patients. Incidence was highest in the fifth and sixth decades of life, and 65% of patients were female. For most patients, symptoms were worse at night or with excessive hand use or both. Self-evaluation questionnaires showed total relief of symptoms after operation in 51% of cases, 75% or greater improvement in 31%, and 50% or greater improvement in 10%. The dominant hand was more severely involved in two thirds of the patients and 78% of patients had occupations involving considerable use of their hands, suggesting that an occupational factor might be involved in the genesis or aggravation of median nerve compression.

Use of crocetin in experimental spinal cord injury.

Mongrel dogs with experimental spinal cord injury were treated with the carotenoid compound crocetin. It has been shown that crocetin increases the diffusion speed of oxygen through plasma, and should provide a net increase in oxygen at the level of the capillary endothelial cell. The treated animals showed a significant improvement in recovery rates as compared to controls.

Effect of increasing the plasma oxygen diffusivity on experimental cryogenic edema.

Mongrel cats with experimental cryogenic brain lesions were treated with the carotenoid compound crocetin. It has been shown that crocetin increases the diffusion speed of oxygen through plasma, and should provide a net increase in available oxygen to the capillary endothelial cell. The treated group of animals showed a significant reduction in edema as compared to a comparable control group. It is suggested that oxygen availability is an important factor in vasogenic edema.

Familial cerebral sarcomas.

Four cases of cerebral fibrosarcomas occurring in two families are reported. To our knowledge, no similar cases have been reported. Evidence that a heritable factor is involved in the genesis of some brain tumors is suggested by these cases.

Unusual presentation of a choroid plexus papilloma.

An unusual case of a choroid plexus papilloma which completely isolated the right temporal and occipital horns from the remainder of the ventricular system is presented. The tumor secreted large quantities of cerebrospinal fluid and also bled into this obstructed cavity. A gross total removal was accomplished.

Ependymal cyst of the thoracic spinal cord.

A unique case of an ependymal cyst on the anterior aspect of the thoracic spinal cord in a woman aged 68 years is described. Clinical signs were precipitated by trauma. Recovery of function, while incomplete, was remarkably good after extirpation of the cyst.
